Background Acceptance of the COVID-19 vaccine by health professionals highly influences the communities’ decision to receive the vaccine, because health professionals are perceived to be a reliable source of health information. Hence, this study aimed at assessing COVID-19 vaccine acceptance and associated factors among health professionals in two tertiary hospitals in southwest Ethiopia. Methods A cross-sectional study was conducted among 319 health professionals working in Jimma University Medical Center and Mizan-Tepi university teaching hospital, southwest Ethiopia, from June 30, 2021 to July 30, 2021. Data were collected by a structured self-administered questionnaire and analyzed by SPSS version 23. A multivariate logistic regression model was used to identify independent factors associated with health professionals’ covid-19 vaccine acceptance. Variables with P-value < .25 on univariate analysis were candidates for multivariate logistic regression. Then, variables with P-value < .05 at 95% CI in multivariate logistics regression were considered statistically significant. Results Of the total participants, 232 (72.73%) received COVID-19 vaccines. Among non-vaccinated health care professionals, 82 (94.3%) of them stated, worries about the safety and side effects of the vaccines, as the reason for non-acceptance. Factors such as, friends or families diagnosed with COVID-19 (AOR = .086; CI: 95%, .041–.18; P = .001), and attitudes and beliefs about COVID-19 and its vaccine (AOR = .129; CI: 95%, .037–.449; P = .001), were significantly associated with the acceptance of COVID-19 vaccine. Conclusion More than one-fourth of health professionals who did not accept COVID-19 vaccines require immediate intervention through awareness creation on the safety and adverse effects of the vaccine by the government and other stakeholders. Otherwise, the community may in large reject the vaccine as they trust health professionals.

Introduction Despite the high prevalence of age-associated comorbidities in HIV patients in sub-Saharan Africa, there is a lack of data on their influence on treatment outcomes in HIV patients. Therefore, this study aimed to assess the impact of age-associated comorbidities on responses to antiretroviral therapy (ART) among people living with HIV. Methods A hospital-based nested case–control study was conducted among adult HIV-infected patients at the Jimma Medical Center from January 3 to June 2, 2022. Data were recorded by interviewing the patients and their medical chart and analyzed using The Statistical Package for Social Science (SPSS) v. 23, and at p <0.05. The Results The overall immunological and virologic failure rates were 13.8% and 13.4%, respectively. Being male [AOR = 3.079,95% CI (1.139–8.327)], having age-associated comorbidity [AOR:10.57,95% CI (2.810–39.779)], age ≥ 50 years [AOR = 2.855, 95% CI (1.023–7.9650)], alcohol intake [AOR = 3.648,95% CI (1.118–11.897)], and having a baseline CD4+ count of < 200 cells/uL [AOR:3.862, 95% CI (1.109–13.456) were an independent predictor of immunological failure; Whereas Being alcoholic [AOR:3.11, 95% CI (1.044–9.271)], having a baseline CD4+ count of < 200 cells/uL [AOR:5.11, 95% CI (1.547–16.892)], a low medication adherence [AOR:5.92, 95% CI (1.81–19.36)], bedridden baseline functional status [AOR:3.902, 95% CI (1.237–12.307)], and lack of cotrimoxazole prophylaxis [AOR:2.735,95% CI (1.084–6.902)] were found to be an independent predictor of virologic treatment failure, but being younger (age < 50 years) was protective for virologic failure. Conclusion Out of the eight patients who were treated for HIV at least one patient had developed immunological and/or virological failure. Age-associated comorbid chronic non-communicable diseases highly influence immunological outcomes compared with virological outcomes. Health providers should pay attention to age-associated comorbidities, encourage lifestyle modifications, and counsel on medication adherence to improve clinical outcomes in patients with HIV.
